The answer is A!!! Hope that helped :)
Answer:
3x+8=0
x=-8/3The face of the denominator must be 0
And the face and denominator of the fraction must be positive
Step-by-step explanation:
The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
